Licence conditions for pollution studies and reduction programs

Licence number: 13426
Title: Investigate and Control Landfill Gas and Odours
Start date: 01 Sep 2021
Licence Condition
U1.1  Background During April to June 2021, the EPA identified offensive odours being emitted from the premises and also received a large number of community odour complaints. This condition requires investigations and reporting to be undertaken by the licensee to implement improved management practices and address odorous emissions. AimTo investigate, develop, & implement works to minimise / manage landfill gases and eliminate off-site odours, as well as provide information to the community on these works, and on future incidents or events that could lead to offensive odour emissions from the Premises. U1.2  Landfill Gas Management PlanThe licensee must: a)  In consultation with the EPA, finalise the Landfill Gas Management Plan (LFGM Plan) to manage landfill gas and prevent the emission of any offensive odour from the premises by 30 September 2021. b)  submit all required documentation to the Department of Planning, Industry and Environment to implement and commission the proposed permanent flaring system by 30 November 2021. c)  update the subsurface landfill gas monitoring plan (SLGM Plan) to comply with Section 5.3 of the EPA’s Landfill Guidelines by 30 September 2021. d)  provide the EPA with an installation and commissioning report which details the installation of the system and includes “as constructed” diagrams for the temporary installed 3 flares and associated flaring system by 22 September 2021. Note: If off-site odours persist following the implementation of the gas management system, the EPA will require further investigation and works to address these odours. Note: Following the review of the LFGM Plan and SLGM Plan EPA will add conditions to the licence relating to: -  Implementation of the LFGM Plan and SLGM Plan. -  the operation, performance and monitoring of the flare/s following the commissioning of the permanent flaring system and may propose further condition/s to oversee the implementation of improvement works. U1.3  Community Engagement Strategy (a)  The licensee must update its Community Engagement Strategy to keep the community informed of the progress of works to rectify landfill odours, the systems in place to manage odour risks, contemporary system upsets or scheduled maintenance that might increase the risk of odours, and any other environmental matters at the premises. (b)  The information presented in the strategy, must include, but may not be limited to; ·  a description of the cause of the odours, ·  proposed short-term and longer-term odour management works or options, ·  the progress to date on these works and options, and ·  contact details for community members to make a report or contact a representative of the licensee. The strategy could include delivery of information through mediums such as; the licensee’s website, targeted letterbox drops, articles in printed news media or social media sites. (c)  A copy of the Community Engagement Strategy must be provided to the EPA at least one (1) week before the due date. (d)  The Community Engagement Strategy must be placed on the Licensee’s website and implemented by the due date. Due Date: 22 September 2021  U1.4  Amended Filling Plan The licensee must engage a suitably qualified expert/s to prepare and submit to the EPA an updated Filling Plan for the premises. The Plan must include details on: a.  how the placement of waste and application of daily and intermediate cover material will be managed to minimise absorption of surface water into the waste mass, such as ensuring a minimum 2 % grade to facilitate the drainage of rainfall from the landfill surface as described in section 8 of the Environmental Guidelines: Solid Waste Landfills (EPA, Second Edition 2016). b.  The staging of waste emplacement, including a detailed filling strategy demonstrating how the various outcomes relating to compaction, gas management, surface water management and leachate management have been considered and will be achieved c.  How landfilling over previous areas of intermediate and daily cover will be managed to reduce the risks of perched leachate and impeded gas flow d.  The maximum total tipping face size, and maximum area not covered by intermediate cover e.  The management measures to be put in place during modifications to gas and leachate management infrastructure during lifts to mimimise risk of off-site offensive odours. Due Date: 30 September 2021 Note: Following the review of the plan, the EPA may propose further licence condition/s to require implementation of the Plan or relevant components.
